<h1>7. Packages<a class="headerlink" href="#packages" title="Permalink to this headline">¶</a></h1>
<p>This section gives a quick overview of the add-on packages that extend
LIGGGHTS(R)-PUBLIC functionality.</p>
<p>LIGGGHTS(R)-PUBLIC includes optional packages, which are groups of files that
enable a specific set of features.  For example, force fields for
molecular systems or granular systems are in packages.  You can see
the list of all packages by typing &#8220;make package&#8221; from within the src
directory of the LIGGGHTS(R)-PUBLIC distribution.</p>
<p>See <a class="reference internal" href="Section_start.html#start-3"><span>Section_start 3</span></a> of the manual for
details on how to include/exclude specific packages as part of the
LIGGGHTS(R)-PUBLIC build process, and for more details about the differences
between standard packages and user packages in LIGGGHTS(R)-PUBLIC.</p>
<p>Below, the packages currently availabe in LIGGGHTS(R)-PUBLIC are listed.  For
standard packages, just a one-line description is given:</p>

<p>The &#8220;Doc page&#8221; column links to either a portion of the
<a class="reference internal" href="Section_howto.html"><em>Section_howto</em></a> of the manual, or an input script
command implemented as part of the package.</p>
<p>The &#8220;Example&#8221; column is a sub-directory in the examples directory of
the distribution which has an input script that uses the package.
E.g. &#8220;peptide&#8221; refers to the examples/peptide directory.</p>
<p>The &#8220;Library&#8221; column lists an external library which must be built
first and which LIGGGHTS(R)-PUBLIC links to when it is built.  If it is listed as
lib/package, then the code for the library is under the lib directory
of the LIGGGHTS(R)-PUBLIC distribution.  See the lib/package/README file for info
on how to build the library.  If it is not listed as lib/package, then
it is a third-party library not included in the LIGGGHTS(R)-PUBLIC distribution.
See the src/package/README or src/package/Makefile.lammps file for
info on where to download the library.  <a class="reference internal" href="Section_start.html#start-3-3"><span>Section start</span></a> of the manual also gives details
on how to build LIGGGHTS(R)-PUBLIC with both kinds of auxiliary libraries.</p>
